Question 1129736

Your matrix


{{{matrix(3,4,
1,	1,	1,	14,
0,	2,	3,	-14,
0,	-16,	-24,	-112)}}}



Find the pivot in the 1st column in the 1st row


{{{matrix(3,4,
1,	1,	1,	14,
0,	2,	3,	-14,
0,	-16,	-24,	-112)}}}



Make the pivot in the 2nd column by dividing the 2nd row by 2


{{{matrix(3,4,
1,	1,	1,	14,
0,	1,	3/2,	-7,
0,	-16,	-24,	-112)}}}


Eliminate the 2nd column

{{{matrix(3,4,
1,	0,	-1/2,	21,
0,	1,	3/2,	-7,
0,	0,	0,	-224)}}}


Solution set: there is {{{no}}}{{{ solution}}}
